Abstract

The utility model relates to the technical field of a battery, in particular to a novel electric core, which comprises a metal case and an inner electrode, wherein a recessed part is formed on one side surface of the metal case, the bottom surface of the recessed part is provided with a through hole, the inner electrode passes through the through hole and is not in contact with the recessed part, the novel electric core also comprises an insertion connection terminal, the insertion connection terminal forms the insertion connection fit with the recessed part and the inner electrode, both electrodes of the insertion connection terminal are respectively in contact with the recessed part and the inner electrode and are respectively connected with conducting wires, and in addition, a current-limiting protecting device is also arranged on a circuit of the insertion connection terminal. After the utility model adopts the structure, the insertion connection terminal can be directly connected with the electric core in the electric core assembly, and is then connected through auxiliary devices such as a battery protection panel and the like which are connected with conducting wires of the insertion connection terminal, so the size increase is small for the electric core per se, and the utility model is favorable for saving the space occupied by the electric core. In addition, the current-limiting protecting device is also arranged on the circuit of the insertion connection terminal, and the use safety of the electric core can be further enhanced.

Description

A kind of novel electric core

Technical field:

The utility model relates to the battery technology field, refers in particular to a kind of novel electric core.

Background technology:

The employed batteries of most of products such as existing mobile phone, digital camera mostly are lithium battery, the general design of the electric core of lithium battery is rectangular shape, mainly constitute on its structure by electrode in metal shell and, metal shell inside holds materials such as chemical reaction solution, and its two poles of the earth are then by metal shell and interior electrode difference " taking on ".In the existing core strueture, the metal shell surface is all designed and is complete plane, offers a through hole so that interior electrode exposes by a side wherein then, and for example baffle, clamped nipple etc. are connected the mode by welding with external accessory again.This frame mode makes the volume of electric core heighten easily, thereby need take the plastic cement housing of more usage space and Geng Duo usefulness material, makes troubles to its use.And the operation of weld job also comparatively bothers and contaminated environment.

The utility model content:

The purpose of this utility model is to overcome the above-mentioned weak point of existing battery battery core, and a kind of novel electric core is provided.

The utility model realizes that the technical scheme that its purpose adopts is: a kind of novel electric core, comprise metal shell and interior electrode, wherein: a side of described metal shell forms a recess, and the bottom surface of described recess offers through hole, and described interior electrode is by passing in the described through hole and not contacting with recess; It also comprises an inserting terminal that cooperates with described recess and interior electrode formation grafting, and the two poles of the earth of described inserting terminal contact and be connected with respectively lead with described recess respectively with interior electrode, and also are provided with limiting protector in the circuit of described inserting terminal.

After the utility model adopts said structure, in electric core assembling, can directly be connected by inserting terminal with electric core, connected by the auxiliary equipment such as battery protecting plate that are connected with the lead of inserting terminal, therefore the volume increase is very little itself for electric core, helps saving its shared space again; And in the circuit of inserting terminal, also be provided with limiting protector, can further add the fail safe that the forceful electric power core uses.

Description of drawings:

Fig. 1 is the structural representation of a kind of embodiment electricity of the utility model core main part;

Fig. 2 is the sectional structure chart of Fig. 1 embodiment;

Fig. 3 is the structural representation of the another kind of embodiment electricity of the utility model core main part.

Embodiment:

Below in conjunction with specific embodiments and the drawings the utility model is further specified.

As shown in Figure 1, 2, novel electric core described in the utility model comprises metal shell 1 and interior electrode 2, metal shell 1 roughly is rectangular structure, a side therein forms a recess 11, present embodiment center dant 11 is cylindrical, the bottom surface of described recess 11 offers through hole 110, and the external diameter of electrode 2 is big in these through hole 110 apertures, to guarantee that interior electrode 2 is by passing in this through hole 110 and not contacting with the bottom with the inwall of recess 11; It also comprises an inserting terminal 3 that cooperates with described recess 11 and the 2 formation grafting of interior electrode; this inserting terminal 3 is the annular column structure; its periphery all encloses the metal contact to contact with interior electrode 2 with described recess 11 respectively with inwall; the metal contact also is connected with lead 4 respectively; and also be provided with limiting protector 5 in the circuit of described inserting terminal 3; in use, limiting protector 5 can be realized the two-fold protection to electric core with baffle, so that electric core obtains better security performance.

Perhaps, can also adopt core strueture as shown in Figure 3, promptly form a cutting part 11 ' in the one bight, interior electrode 2 stretches out and is positioned at this cutting part 11 ', peg graft with inserting terminal 3 again, the outer wall metal contact of inserting terminal 3 contacts with a sidewall of cutting part 3 and gets final product, and its effect is consistent with embodiment 1.

Obviously, above-mentioned is two specific embodiments of the present utility model, is not to be used for limiting protection range of the present utility model.Shape, size and the limiting protector position on inserting terminal of the recess shapes on the metal shell of electricity core, size, position, inserting terminal etc. can change according to the design needs; as long as its structural principle is consistent with the utility model, then also should be within protection range of the present utility model.

Claims

1. novel electric core, comprise metal shell (1) and interior electrode (2), it is characterized in that: a side of described metal shell (1) forms a recess (11), the bottom surface of described recess (11) offers through hole (110), and described interior electrode (2) is by passing in the described through hole (110) and not contacting with recess (11); It also comprises an inserting terminal (3) that cooperates with described recess (11) and interior electrode (2) formation grafting; the two poles of the earth of described inserting terminal (3) contact and are connected with respectively lead (4) with described recess (11) with interior electrode (2) respectively, and also are provided with limiting protector (5) in the circuit of described inserting terminal (3).
